Iron contained in aluminum alloys is an impurity that cannot be removed, and it causes porosity in the solidification process and forms intermetallic compounds, which negatively affects mechanical characteristics; therefore, Fe intermetallic compound control is required. Therefore, in this study, an analysis of the microstructure and mechanical properties of aluminum alloys produced by injecting Na₂B₄O<SUB>7</SUB>·10H₂O with a maximum solubility of hydrogen was conducted. After the addition of Na₂B₄O<SUB>7</SUB>·10H₂O, the size of the Fe-rich intermetallic AlSi7Mg0.3 compound reduced, and the needle-shaped Fe intermetallic phase transformed into Chinese-script-shaped in the AlSi10MnMg alloy. Further, the fraction of the Fe intermetallic compounds reduced by 0.17 % and 0.15 % in AlSi7Mg0.3 and AlSi10MnMg, respectively, after the addition of Na₂B₄O<SUB>7</SUB>·10H₂O, and the secondary dendrite arm spacing and size of the Si particles increased. In the alloys with the addition of Na₂B₄O<SUB>7</SUB>·10H₂O, the increased secondary dendrite arm spacing and blocky Si reduced the tensile strength of the AlSi7Mg0.3 and AlSi10MnMg alloys to 11.45 MPa and 11.78 MPa, respectively. In contrast, the transformed Fe intermetallic compounds increased the hardness of the Al matrix to 4 HV and 2.53 HV in AlSi7Mg0.3 and AlSi10MnMg alloys, respectively.
